Ending A custom story

[XeOnTricks]

How are you leaving the map? If you're leaving through a level door without an assigned map, it will crash. If you're just going to end the game when you leave the door instead of actually loading another map, then just select the current .p as the destination.

so are you saying to mark the first map as the destination? which i did but the credits didnt show up it just put me back into the map. Im wondering what im doing wrong .
